well when you drive cam bearing they can get a hi spot in them that why i have cam s to check that if i do not build the engine .so i know they will not grab sounds like you have a hi spot . i use a bearing scraper and work the hi s off then i buff with a worn red scotch bright or a new gray pad . but before i do any thing i first chamfer the new bearings before i drive them .clean the cam housing bores with a ball hone and rework the block if needed for some lead helps to and one pc bearings work better then two pc with the but lock on them . if you can turn if by hand you may be ok but i like them to be some what free lube it well if you think you can get away with it sounds like the lobe nick more then two ? if so you can have a hi spot from that .if you did not take the engine apart make sure your oiling holes line up i drive the front one thru the driver thru back of the block with the line cone so it drive strait . if you drive #1 and #2 thru the front of the block you ods are good you do have a hi spot
